Problems solved by technology

[0008] Due to the above requirements, many electronic pastes are basically unable to meet them. Although DuPont and other companies have also developed some electronic dielectric pastes to match stainless steel plates, they are expensive and require multiple printings. Adding organic binders and low production efficiency make people discouraged

Embodiment Construction

[0034] Below in conjunction with specific embodiment the present invention is described in further detail:

[0035] Electronic dielectric materials on high-power stainless steel plates, which are mainly made of glass-ceramic powder by high-temperature sintering and melting of non-metal oxides, and then added with water to make it into a slurry. The ratio of glass-ceramic powder to water is (50-90) : (50~10), the electronic dielectric material is composed of glass ceramics, wherein the non-metallic oxide includes the following components by weight percentage:

[0036] SiO2: 20-80%, Al2O3: 0.5-20%,

[0037] Cr2O3: 0.5-8%, CaO: 10-50%,

[0038] TiO2: 0.5-15%, ZrO2: 10-30%,

[0039] ZnO: 1~10%, Na2O: 1~5%,

[0040] K2O: 1-10%, MgO: 0.1-10%.

[0041] The above non-metal oxides are smelted in proportion to obtain glass-ceramic powder, and then water is added to the glass-ceramic powder to obtain electronic dielectric material.

[0042] The preparation method of the electronic d...

Abstract

This invention relates to a high-power electronic medium material on the stainless steel plate with superior insulating properties and good printing characteristics and a method for manufacture, which does not need to be printed and sintered in many times. The first step is to prepare the electronic media materials, match the non-metallic materials according to weight percentage, mix them then to sinter the mixed materials to microcrystal glass powder, then add raw materials and water in the glass powder to get a slurry electronic medium to be sprayed on the stainless steel to be sintered to become an insulated medium layer.

Description

technical field [0001] The invention relates to a dielectric material for a stainless steel plate of a heating element, in particular to an electronic dielectric material on a high-power stainless steel plate and a preparation method thereof. Background technique [0002] At present, the heating series used in the market include positive temperature coefficient thermistor material (referred to as PTC) heating components, carbon slurry electric heating film heating components, but their heating is slow, low power, low temperature and are subject to many restrictions, there are also on the market Many high-power, high-temperature resistance wire heating components and nickel-chromium heating components have short lifespan, low thermal efficiency, and unsafe etc., so that their application fields are subject to many restrictions. Later, many foreign companies developed various Electronic paste, which is applied to non-metallic materials such as ceramic substrates and polymer ma...
